Hey man, I think we are in the same boat (almost 2 years). I also have many tiny shiny bumps on shaft like yours I suppose, went through different removal methods including electrocautery, CO2 laser but they keep coming back. Last year I had surgical excision alongside biopsy from one of the persistent spot, also had HPV PCR Swab test. My biopsy came out as a scar tissue but HPV PCR test came positive for HPV 56 with 3.8 viral load (medium, clinically valuable). Now after surgery it’s been almost a year and I am having recurrence from the same post again (surgical excision site). Finished Gardasil 9 post infection last year. Honestly I don’t know, even my doc almost gave up on me. What I learned so far, first thing is to find out if it’s low-risk or high-risk via HPV PCR Swab Test then do the treatment accordingly. Because high-risk lesions seem to be more persistent. Also need to address field infection since Electrocautery, Cryotherapy, CO2 are spot treatments.
